Abstract
Embodiments of the present invention provide a communication method for a carrier aggregation system, relating to the field of communication technologies, and being invented for the purpose of effectively ensuring normal communication between a base station and a user equipment. The communication method includes: receiving physical downlink share channel PDSCH information sent by a base station through a subframe n of a secondary cell; and if a subframe n of a primary cell is a downlink subframe: feeding back an ACK/NACK of the sent PDSCH information on a subframe m or a subframe p of the primary cell, where the m, determined according to the ACK/NACK timing relationship to which the subframe n of the primary cell corresponds, is a subframe index of a subframe that feeds back the ACK/NACK of the PDSCH of the subframe n of the primary cell in the primary cell, and the p, determined according to the ACK/NACK timing relationship to which the subframe n of the secondary cell corresponds, is a subframe index of a subframe that feeds back the ACK/NACK of the PDSCH of the subframe n of the secondary cell in the secondary cell. The present invention may be applied to a carrier aggregation system.
